X field is a gas-oil field which has been producing for more than 30 years with a high pour point oil characteristic that indicates the oil can cease to pour when it is affected by low ambient temperature. X-1 processing plant is one of the plants located in field X which is connected to 7 production wells by a 10.1 kilometers pipeline. The well performance simulation is generated using Prosper Software. The simulation is done for 7 production wells connected to the X-1 processing plant by using the wells production history data, well sketch figures, and open hole log reports as the input data. The simulation indicates that Well A, B, C, D, E, F, and G do not have the formation damage problem as having the negative skin value after the result is matched with the actual production rate. After analyzing the formation damage of each well, the flowline temperature is generated by using Pipesim Software and the possible pour point problem position in the pipeline is evaluated at the average and the lowest ambient temperature in field X. The simulation of flowline temperature using Pipesim Software shows that the pipeline which connects all the well to X-1 processing plant has the pour point problem with 55 % area of pipeline at the average ambient temperature and 94.68 % area of pipeline at the lowest ambient temperature. Then to fix the problem, this study proposes solutions which includes injection of pour point depressant, application of intelligent pigging, and injection of xylene.
